Question

I need help on this one question I am stuck on it.

Answer 1

Given:

8.90ft³ for 30 balloons

Let h be the volume of helium and b be the number of balloons.

Using proportion;

b/h = 30 /8.90

Multiply both-side by h

$\frac{b}{h}\times h=\frac{30}{8.90}\times h$$b=\frac{30}{8.90}h$

Hence, the answer to blank 1 is the above.

when b=50, substitute for b in the above and solve for the volume (h).

That is;

$50=\frac{30}{8.90}h$

Multiply both-side by 8.90/30

$50\times\frac{8.90}{30}=h$

$14.83=h$

Hence, the answer to blank 2 is 14.83ft³.
